How to fill out energy for phase changes?

1. Determine the substance undergoing a phase change. It can be a solid, liquid, or gas.
2. Identify the initial and final phases of the substance. For example, if it is changing from a solid to a liquid, the initial phase is solid and the final phase is liquid.
3. Look up the specific heat capacity of the substance for each phase involved. This value indicates how much energy is needed to raise the temperature of one unit mass of the substance by one degree Celsius.
4. Calculate the temperature change required for the phase change. This can be done by subtracting the initial temperature from the final temperature.
5. Multiply the mass of the substance by the specific heat capacity of the initial phase and the temperature change to obtain the amount of energy needed to raise the temperature of the substance from its initial phase to the phase change temperature.
6. Add any additional energy required for the actual phase change. For example, for a solid to liquid phase change, you need to consider the latent heat of fusion, which is the energy required to change a solid into a liquid at the same temperature.
7. Calculate the total energy required by summing up the energy for temperature change and the energy for phase change.

Who needs energy for phase changes?

1. Substances undergoing phase changes require energy. This can include solids melting into liquids, liquids evaporating into gases, or gases condensing into liquids.
2. Energy is needed to overcome the forces of attraction between particles in the substance and to disrupt their arrangement.
3. Different substances have different energy requirements for phase changes, depending on their molecular structure and intermolecular forces.
4. External factors such as temperature, pressure, and environmental conditions can also influence the energy needed for phase changes.
5. Energy is vital for phase changes to occur, as it allows the substance to transition from one phase to another while maintaining its overall composition.
